The present invention relates to heating and ventilating apparatus, and more particularly to the means for inducing a draft or circuit of air through a building and heating flues of a dwelling or the like. An object of this invention is to providea device, which may be installed in a dwelling or other house for operating in connection with the heating plant of the house to set up or force air currents through the house, so

that the cool air may be more rapidly returned to the furnace or heater and the warm air be more evenly and rapidly difiused throughout the interior oft-he house.

Another object of the invention is to'pro-' vide an air current impelling means, which includes an-electric motor and a fan so mounted that the vibration of the apparatus when running will not be transmitted to the house structure and also the noise incident to the running of the motor and fan will be reduced to a minimumand the noise vibrations be arrested through the medium ofisound nonconducting insulators. L

y The invention also aims to provide agrating for insertion in the floor of the building and through which the air is adapted to be forced by the device, and to provide an improved mounting and connection between the floor and the grating and the grating and the fan, so that the entire device may be easily and quickly installed as, a unit either in the floor of a house adjacent the heater, or in the upper part of a pipeless furnace for assisting and forcing the circulation of air through the furnace and through the house.

The invention still further aims to provide an improved mounting for the motor forthe purpose of absorbing vibration and noise and for yieldably supporting the motoragainst shock and the like, which would otherwise be imposed on the apparatus-tending to disturb its adjustment and attachment'to the grating or'adjacent parts of the building.-

With the foregoing and other-1 objectsin view, the invention will be more fully de-- scribed hereinafter, and will be more particularly pointed. out in the claims appended hereto.

Inthe drawings, wherein like symbolsre to like or corresponding parts throughout all the several views Figure 1 is a verticalsection taken through a pipeless furnace, shown diagrammatically and in which is mounted animproved draft impelling. device constructed according [to this invention. r q 1 Figure 2 is a fragmentary enlarged section taken through the device'in its position with respect to one sideof the wall of the furnace; Figure 3 is a sectional ,view taken through a portion of the flooring of a building, show ing a" slightly modified form of the device applied thereto. 1 I Figure 4. is a fragmentary section of a modified form of grating and motor supporting connection, and

I Figure 5 is a'fragmentary sectional .view

through a portion ofa modified form' of gratingand suspension means for the motor and the fanf f .I Referring to the drawings, 10 designates the outer wall of-a pipeless furnace and 11 an inner wall-or partition, Which isconcentrically, spaced withinthe wall 10 andwhich extends from approximately the upper end of thewall 10 to a point spacedvabove the lower end or bottom 12 of the furnace. 7 Q

Such arrangement provides a cold air passage 13 about the inner wallof the furnace and which opens through the top of the furnace to recelve cold airfrom the-room or compartment above thefurnace, the cold air beingconducted downwardly through the passage 13 and about thelower end of the partition 11,.and then upwardly into contact with the heating drum 14, and combus tion chamber 15 which are supported: upon the ash pit 16, as diagrammatically shown. The air which is heated in the inner chamber'contained within the partition 11 rises upwardly through the top of the furnace and through a grating 17 seated inthe floor or over the'top of the furnace topermit the warm air to rise through the central flue or portion of the furnace. The cooler air in the room accumulates in the bottom and is drawn toward the upper end ofthe furnace 10 by the ascending heated air from the furnace, the cooler air entering downwardly through of the grating 17, and the brackets 18- are provided with downwardly extending hooks 20 upon which coil springs. 21 are engaged for supporting the impelling device of this e passage 13 may becarried off to the fan. This invention. p

There 1s provlded a spider or frame consisting of a ring 27 having a pluralitypof radiating arms 22, which arms are mounted on the lower ends of springs 21. These arms carry a circular shield 23 adapted to protect the sprin'gs 21 'against'hot air which is impelled by a fan 24, which is disposed in the upper portion of the hot air passage formed by the inner wall 11. The fan 24 is mounted a on the upper end of the shaft 25 0f an electric motor 30.' The ring 27 supports an annular resilient ring 28 on which are hung supporting hooks or members 29. The motor is clamped to the lower ends of these hooks by bolts 31 which pass through ears on the lower inturned portions of the hooks and also through cross bars 31 extending over, the

. to the upper ends of the bolts 31and' which is spaced about the motor a distance sufiicient to provide an upwardly directed annular passage about'the motor. Q r

'The casing 32 in its top has an opening adapted to directlyopen centrally above the motor 30, and an annular wall or flange 34 is provided on the hood 32 and extendsup- Wardly into proximity to the under side of the fan 24, so that the lattermay be operated not only to raise the heated air outside of the hood 32, through the top of the furnace 10, but the fan 24 also draws a quantity of cold air upwardly through the middle of the hood 32 and about the motor 30. Such action commingles the cold air with the warm air so as to produce a more'even temperature in the house, andalso produces a continuous current of relatively cool air against'and about coupled to the upturned end of an air duct 35,

which first extends downwardly from the hood 32, and thence laterally thereof'to provide a hollow arm 36 which passes between a furnace or the like. r

and in spaced relation from thesprings 21 and the spider arms 22. The hollow extension 36 extends upwardly and outwardly from the lower casing part 35 and is provided upon its upper end with a bellows connecting member 37 adapted for connection at its free end with a flange or nipple'38 formed upon the inner wall 11 of the furnacenear the top thereof, the wall 11 being recessed within the flange 38 .to provide an opening through Which cold'air 'passing'downwardly into the cold air is thus carried directly to the fan and forced upwardly and outwardly by means of the fan to commingle with the heated air outside of the hood 32. r

The natural circulation'of the air is thus augmented not only bythe impelling device, which naturally forces the circuit, but also by admixing a portion of the returning cold air with the outgoing heated air from the furnace, so as to moderate the heated air to such an'extent that the entire cubic contents of the building is maintained. at substantially a uniform temperature. 1

In such cases where it is desired to produce a'forced circulation of air in connection with a hot air furnace of any type, the floor 39 of tween a-pair of joists 41. The "3' oists 41-are utilized for supporting a pair of brackets 42,

which are secured againstthe inneropposite faces of the joists 'in'proximity to the grating 40and which have hooks 43 from which are suspended springs 44' carrying'upon. their lower ends the arms of a spider 45, which have cushioning-blocks 46 there'beneath, as shown in Figure 3, so as 'to'not only yieldingly support the spider 45, but alsofdeaden or arrest noise vibrations incident to the operation of a motor 47 which is seated in the spider 45 by means of the resilient ring 28. In this casethemotor 47 may be provided with a fan 48, the blades of which are so set as to effect a downward suction of-air through the grating 40 fromthe space above the floor 39 down througlrthe floor and into an air receiving casing or duct 49, which may be placed in communication withthe cold air intake of This type of device I may bev readily installed in a dwelling or other, building-without disturbing the installation of the hot air heatin unit. I Y "In' igure4 a slight modification is shown the flange 51 to accommodatea resilient block '54 of rubber or the like and upon'which a grating 55 is seated. This block 54 is utilized for supporting the upper end ofa motor wherein the floor 50 has mortised or seated V suspending spring 56 and is apertured to receive the upwardly extending extremity 57 of the spring which may be enlarged or headed in any suitable manner, as shown in Figure 4: to hold the end 57 from moving downwardly through the block 54. V

The modification shown in Figure 5 discloses a grating 58 to the under side of which may be integrally cast or formed a bracket 59 carrying a hook 60 disposed beneath the grating 58 to receive the upper end of a motor supporting spring 61.

In all forms of the invention it will be noted that the electric motor and its fan are mounted yieldingly upon springs or the like so as to absorb vibration incident to the running of the motor and the fan, and are also mounted upon resilient elements adapted to absorb or arrest sound vibrations, so that the motor and fan may be run without producing noise or vibration in the building.

It will also be noted that the devices of this invention are of such a nature that they may be quickly and easily installed in a pipeless furnace or in a house without modifying either the furnace or the house to any appreciable extent.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims Having thus described my patent, I claim:

1. In combination with an air heating device having a heated air outlet passage and a return cool air passage, a motor, a fan mounted on the motor, said motor and fan being located in said heated air outlet passage, and means for by-passing a quantity of the air from the return cool air passage disage directly to the motor and fan for protecting the motor against injury by the hot air'and for commingling the hot air with the small proportion of the returned cool am 4:.
